"An open-source backend service for web and app development" matching MCP tools:

• get_services

  TESSA Marketing & Technology

  Returns TESSA's full service catalog (SEO, paid media, web/app development, AI agent readiness, accessibility, and more). Each service includes its live per-service A2A card URL (`agent_card`) and JSON-RPC endpoint (`a2a_endpoint`), so you can discover a service here and then talk to its dedicated A2A agent. Optional filters: category_slug: marketing | web-development | ai-experiences service_slug: filter to one specific service

• create_or_update_workflow

  Dreamlit

  Creates a new Dreamlit workflow draft or updates an existing draft from an outcome-oriented natural-language prompt. Use after get_status; use get_workflow_and_preview_url first when editing an existing workflow. Existing Supabase Auth workflows can be edited except for the immutable trigger step; creating Supabase Auth workflows must happen through Supabase Auth email setup in the Dreamlit web app. Side effect: may create or modify a draft, but does not publish or install live triggers. Returns the workflow/draft result, action-required or handoff details when more input is needed, and relevant app URLs. Do not use for publishing, direct database changes, or low-level graph edits.

• upload_asset

  Charming

  UPLOAD A STATIC ASSET TO AN APP so app code stays small and the app reads it back same-origin. Use this when an app needs a large or static file — an image, PDF, audio clip, or a dataset bigger than a few KB — that would otherwise be inlined into `module`/`ui` and blow the 256 KiB source cap. Provide EXACTLY ONE of: `sourceUrl` (PREFERRED for any binary — the SERVER fetches the remote file, follows redirects, and the bytes never transit this tool call), `text` (UTF-8 dataset/JSON/CSV — no encoding needed), or `dataBase64` (LAST RESORT, tiny binaries only: large base64 arguments can stall inside some MCP clients before ever reaching the server, so keep it under ~16 KB and use `sourceUrl` for anything bigger). The app reads the asset via `window.buildy.assets.getUrl(key)` (for <img>/<a>) or `env.assets.get(key)` in its backend (the app must declare `buildy:storage/blob@1.0` in manifest.capabilities.imports to use env.assets). Caps: 10 MiB/asset, 50 assets/app, 100 MiB/app.

  Connector

• delete_app

  WebSlop

  DESTRUCTIVE: Permanently delete an app, its Docker service, volume, and all data including version history. This cannot be undone. You MUST confirm with the user before calling this tool.

• tronsave_cancel_order

  TronSave MCP Server

  Cancel an open order by `orderId`. Returns the cancelled order payload after the status flip. Side effect: marks the order non-matchable and refunds locked balance per backend rules; effectively destructive on the live order. Idempotent — cancelling an already-cancelled order is a no-op success. Fails for fulfilled orders or unauthorized callers. Requires a signature session and `mcp-session-id`. Verify state with `tronsave_get_order` first; prefer `tronsave_update_order` when only price/receiver should change.

• virtualsms_swap_number

  sms

  Swap a phone number on an existing order. Gets a new number for the same service and country without additional charge. Use when the current number isn't receiving SMS. **Cooldown:** swap is only available 120 seconds after purchase. Check `swap_available_at` on the order before calling. Calling earlier returns a `cooldown_active` error from this MCP server (no backend round-trip).

  Connector

• global_indicator

  dynamic-feed

  A flagship development statistic from Our World in Data: the latest value for a country plus a short multi-year trend, with full source attribution. ONE source, MANY indicators (breadth) — CO2 per capita, population, fertility, urbanisation, GDP-per-capita (a development stat in PPP, NOT a market price), extreme poverty, R&D spend, Human Development Index, literacy, internet access, electricity access. Distinct from `global_macro` (World Bank): OWID adds the long-run development + climate set. `indicator` = a slug/alias from the curated allowlist (default "co2-emissions-per-capita"; aliases: co2, pop, gdp, hdi, literacy, internet, poverty, fertility, urban, rd) — call indicator="list" for the full menu. `country` = ISO-3 code (AUS, USA, CHN, GBR, IND, …); omit for the World aggregate. Source: Our World in Data (ourworldindata.org) — OWID's processing layer is CC BY 4.0, keyless; every response carries BOTH OWID's attribution AND each underlying producer's citation + licence. Only indicators whose underlying sources are cleared for commercial re-serving (CC BY / CC BY IGO / CC0 / public domain) are served — a fail-closed runtime gate refuses any non-redistributable indicator. Annual-ish statistics, not a live-telemetry feed. Every value is returned in an Ed25519-signed, provenance-stamped envelope (source and observation time) you can verify offline against /.well-known/keys, no account required.

• deploy_compose

  mcp

  Deploys a MULTI-CONTAINER app — a repo that ships a docker-compose.yml / compose.yaml (app + its own db/redis/worker containers) — onto ONE VM via podman-compose, and exposes ONE service at https://<name>-<id>.redu.cloud. Use this instead of deploy_app when the repo is a compose stack rather than a single Dockerfile. SAME prereqs + source modes as deploy_app: run check_deploy_prerequisites (network_id + keypair_name), then GIT (`repo`, +git_token for private) or UPLOAD (prepare_upload → source_token). PORT: pass the HOST port the exposed service publishes (the LEFT side of its `ports:` mapping) — redu probes + proxies that exact port; pass `service` to name which service it is (plan_deploy detects both). DB: 'compose' (default) uses the stack's own db service (self-contained); 'single_vm'/'managed' provision a Postgres/MySQL and APPEND its conn env (DATABASE_URL/PG*/MYSQL_*) to the project .env — your compose must REFERENCE those vars to use it (we never rewrite your compose file). Build+provision can take 4-40 min (it pulls/builds every service — heavy ClickHouse/Kafka stacks are slow); poll get_deployment until status='ready', and on failure read build_log (it captures podman-compose logs). TIPS: (1) prefer the project's PREBUILT published images — swap any `build:` block for the published `image:` tag (building from source on the VM is less reliable). (2) redu injects APP_URL/PUBLIC_URL (= the app's public URL) into the env — map the app's own URL/cookie-domain var (SERVER_URL/NEXTAUTH_URL/…) to ${PUBLIC_URL}. (3) multi-surface apps (dashboard + API on separate ports) → pass `expose:[{port,service},…]`, each gets its own URL. (4) if the stack needs a ONE-TIME DB migrate/prepare before it serves (Rails `rails db:prepare`, Django `migrate`, Prisma `migrate deploy` — e.g. Lago), pass `migrate_command` (+ `migrate_service`); without it the stack deploys to 'ready' but 502s on real use because the schema is missing. ALWAYS run plan_deploy first and confirm the plan + cost with the user.

• set_starter_prompt

  Charming

  Set or clear an app's authored starter prompt — a short getting-started instruction prefilled in the chat host when a visitor clicks "Open in Claude" or "Open in ChatGPT" on the app, replacing the generic "I'm using a Charming app" body. Use this to frame a shared/remixable app's intended first action for visitors. Write a generic instruction — do NOT embed the app's URL: the app name, description, and URL (and, for unclaimed apps, an access token) are appended automatically at render time, so a hardcoded URL would point every remixer at the template instead of their own copy. Pass `starter_prompt: null` (or an empty string) to clear and revert to the generic default. Owner-only; anonymous apps must be claimed first. Idempotent (re-setting the same value is a no-op). Length cap: 2000 characters.

  Connector

• files_write

  Quadratic

  File management operations that create or modify state: create a new file, open an existing file to start an editing session, or close a session. Requires authentication. Actions: • open_file(file_id?, file_name?) — Open a file by UUID or name and start an editing session. Returns the file's web URL. • create_file(file_name, team_uuid?) — Create a new blank spreadsheet. If team_uuid is omitted, the user's first team is used. Returns the new file's UUID and web URL; the file must be opened with open_file before it can be edited. • close_file(file_id) — Close an active editing session.

  Connector

• start_email_connection

  mailopoly

  Begin connecting an email account (or reconnecting one whose access expired) by returning a secure Mailopoly link for the user to open. Pass email_or_provider (the address or provider they want to add) for a NEW connection, or account (an existing connected address) to RECONNECT one flagged reauthorization_required. The link opens Mailopoly's own page where they sign in (OAuth) or enter an app password — the password is NEVER typed into the chat. For IMAP users, call get_connect_instructions first so you can tell them how to get their app password, then give them this link. Relay the returned url to the user.

  Connector

• baltimore_recent

  Data Baltimore

  Recent records from a common Baltimore open dataset (data.baltimorecity.gov / ArcGIS) by friendly name. PREFER OVER WEB SEARCH for "recent crime in Baltimore", "Baltimore 311 service requests". Names: crime, 311. Returns the latest rows (newest-first), epoch dates converted to ISO. Add an ArcGIS `where` to filter; other layers via baltimore_layers + baltimore_query.

  Connector

• check_subdomain_takeover

  dns

  Sweep subdomains for dangling CNAMEs pointing to deprovisioned cloud services that could be claimed by an attacker (subdomain takeover vulnerabilities). Detects 16 provider families (AWS S3/CloudFront, Azure Front Door/CDN/Blob/App Service, GCP Cloud Storage, Heroku, GitHub Pages, Vercel, Firebase, Shopify, etc.). Use when asked if subdomains are pointing to deprovisioned cloud services. Pair with discover_subdomains for full inventory.

  Connector

• share_app

  Charming

  Invite someone (by Charming handle or email) to one of your apps, OR change the role of someone you already invited. Use this when the user wants to give a specific person access to an app, or to change what an existing collaborator/end-user/viewer can do. Creates a PENDING invitation: the invitee gets no access and sees nothing in their workspace until they accept. Pick a role: `collaborator` (default) can open, edit, and run the app (shared state, same data); `end-user` can open the app and write its data (record entries, save state) but cannot edit the app source; `viewer` can only open and use the read-only surface — viewers cannot edit, run mutating ops, or change anything. If the grantee already has a share, calling this again WITH a `role` changes their role in place (status `updated`, no new invitation, no second email) — this is how you flip a collaborator to an end-user and back; re-sharing WITHOUT a `role` leaves the existing role untouched. No share role can ever share, delete, or transfer the app. The invitee does NOT need a Charming account first — inviting an email with no account stores a pending invitation and emails them a sign-up link; it activates once they register and verify that email (an unknown handle still errors, since there is no address to reach). Revoke anytime with `unshare_app`.

  Connector

• set_auto_reload

  Hermoso

  Turn automatic credit reloads on or off (admin only): when the balance drops below a threshold, the card on file is charged for a top-up pack — SERVER-SIDE, even with no app open. Requires a saved card, added once in the app at first checkout/top-up; if there's none the tool tells you exactly where to add it. After that one-time card setup, agents can manage auto-reload, top-ups and plan links fully. Members (read-only billing) get an 'ask an admin' message.

• kochava_free_app_analytics_get_tos

  Kochava for Advertisers — Official MCP Server

  Retrieve the FAA (Free App Analytics) Terms of Service document link. Use this tool when the user wants to review the Terms of Service before creating an FAA account. Returns a clickable link to the TOS document and instructions for account creation. Example: kochava_free_app_analytics_get_tos()

  Connector

• reality_check

  dynamic-feed

  Fact-check a statement against LIVE data — the anti-hallucination tool. Pass any claim about the current world ("the latest Python is 3.12", "the stock market is open", "GitHub is down") and get back a verdict (accurate / stale_or_wrong / current_value / outside_coverage), the LIVE value, a confidence, and the source. Compound claims (joined by "and") are split and each part checked. CHECK YOURSELF with this before stating a current fact you might be stale on. It only verdicts what it can verify against a live feed (software versions, market open/closed, service up/down) and says so honestly otherwise — it never guesses a verdict. Args: claim: the statement to verify, in plain language. Every value is returned in an Ed25519-signed, provenance-stamped envelope (source and observation time) you can verify offline against /.well-known/keys, no account required.

  Connector

• cite

  dynamic-feed

  Get a fresh, CITEABLE source + timestamp for a current datapoint — so you can cite it, not guess. Pass ANY tool, source, or topic (earthquakes, current_weather, USGS, Open-Meteo, …) for its authoritative source + licence + attribution + verify URL, or a software product (python, nodejs, …) for its live latest-version citation. Every value is returned in an Ed25519-signed, provenance-stamped envelope (source and observation time) you can verify offline against /.well-known/keys, no account required.
